→PB1-2
Power box connected to PP1-1 by conduit. Bridges the A/C heat pump/air handler circuit, among other things. The 3-phase for A/c heat pump and air handler is bridged such that the entire 3 phase comes from PP1-1 up to the roof via PB1-2, and a branch switched on the roof by relay comes back down in the same conduit that goes the the roof. This circuit is passed via conduit to the air handler, and switched manually on the bottom of the air handler.

Below is the result of wire tracing done 04/25/2017. Tucker
This junction is a pass through for circuits from PP1-1, PP1-2 and the small fuse box.
*Small fuse box
**lines go through PB1-1->PJ1-1->PB1-2->roof and supply heater fans
*PP1-1
**This circuit feeds through the conduit marked 'B' to the roof and presumably the AC (see note from previous mapping)
*PP1-2
** from conduit 'B', the circuit feeds through the wall behind PB1-2 and into the dock, where it supplies the 220V welder outlet on the back wall above the hydraulic pump.
** from conduit 'C' -> PB1-2 -> PJ1-1 -> PB1-1 -> exit sign over back door, and the outlets above PP1-1
** Conduit 'D' connects PP1-2 and PB1-2, but no wires are run inside.
